/*
 Welcome. In this kata you are required to, given a string,
 replace every letter with its position in the alphabet.
 If anything in the text isn't a letter, ignore it and don't return it. a being 1, b being 2, etc. As an example:
 alphabet_position("The sunset sets at twelve o' clock.")
 Should return "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11" (As a string.)
